如何使用多个嵌套三元运算符返回值

Question

I am looking at using a multiple nested ternary operators. I have 3 values I want to compare. All 3 are integers. For example:

val1
val2
threshold

From all this I want a result of 1 or 0 .

So, if I was to do this using if-else statements, my logic will look like this:

if (val1 - val2 > threshold)
{
    result = 1;
}
else if (val2 - val1 > threshold)
{
    result = 1;
}

So far I have this:

int d = (alpha < 0 ? -alpha : alpha) > threshold ? (alpha < 0 ? -alpha : alpha) : 1;

which, although it compiles, does not give me the same result...

Answer 1

result = (val1 - val2 > thresold) ? 1 : (val2-val1 > thresold) ? 1 : 0;

Or

result = (val1 - val2 > thresold) || (val2-val1 > thresold) ? 1 : 0;

Or

result = Math.Abs(val1 - val2) > thresold ? 1 : 0;

Answer 2

result = val1 - val2 > threshold ? 1 : val2 - val1 > threshold ? 1 : 0

Answer 3

Why not this:

int d = (val1 - val2 > threshold) || (val2 - val1 > threshold) ? 1 : 0;

However, consider carefully if this is more readable than the if statements. Indescriminate use of the ?: operator can make it more difficult to read and comprehend code.
